WIND IYNG=RO LLER FOR MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 271,064, dated January23, 183.

Application filed December 22, 1881. No model.) i

To all whom it may concern:

Be it known that 1, ANDREW H. HAMMOND, of Worcester, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in VVinding- Rollers for Mechanical MusicalInstruments, of which the following is a specification.

The object of my present improvements is to produce a roller on which atraveling musicsheet fora mechanical musical instrument may be wound,and which shall be so light as to acquire but little momentum when inmotion. Such a roller is especially desirable as a takeup roller for themusic-sheet.-

My improvements consist in the combination, in ainechanical musicalinstrument, with a traveling music-sheet, ot' a roller composed ofawooden or other shaft and heads, and a body consisting of a cylindricshell, of paper or other light material.

They also consist in the combination, with such a music-sheet, ot' aroller composed of a wooden or other shaft provided with two heads andan intermediate flange or truck, and a body consisting of a cylindricshell, of paper or other light material, and having a peripbericalrecess containing a device whereby the sheet may be attached.

In the accompanying drawings, Figure 1' representsa longitudinal sectionof a mechanical musical instrument containing rollers embodying myimprovements, Fig. 2 is a top view of the case and rollers of the same,one of the rollers being partly in section; and Fig. 3 is a longitudinalsection of the case of the instrument, a side view of bearings for therollers, and a transverse section of journals of the rollers in thebearings. I

Similar letters of reference designate corresponding parts in all thefigures.

A designates the case of a mechanical musical instrument. B designatesthe reed-board thereof. 0 designates the traveling perforatedIDUSICSIIGGT. D designates the roller on which the music-sheet isnormally kept wound, and E designates the take-up roller on which themusic-sheet is wound during the playing of the instrument.

The take-up roller E consists of a shaft, a, of wood or other suitablematerial, two heads,

b, affixed thereto, hubs c, contiguous to the heads, and preferably madeintegral therewith, an intermediate flange or truck, cl, and a cylindricbody or drum, 6, of paper or other light material, fitting the said hubsand flange 5 or truck.

In the periphery of the flange or truck cl and adjacent part of the bodyor drum 0 is a recess, f, provided near the bottom with a hook, g, fordetachablysecuring the musicsheet thereto. The end of the music-sheet ispreferably provided with a ring, h, capable of engagement with the book9, and this ring may be secured to the music-sheet by a tape or strip,of any strong thin material, passing 6 through the ring, and lapped overeach side of and secured by paste, glue, or otherwise to themusic-sheet.

I prefer to make the heads of the musicroller 1) of paper, bindersboard, leather- 70.

board, or like material, for in that way I can easily and cheaply makethem strong and durable. They project circumferentially beyond the bodyof the roller. One or both the heads of the take-up roller E may be madein the same manner, if desirable.

The headset the rollers used in mechanical musical instruments andcertain other articles are necessarily so thin that when made of woodthey are easily split and broken; but by making them of paper, bindersboard, leatherboard, or like material this difficulty is obviated. Whereused they are pressed onto 8X- tensions of the shalt or body of therollers,

made of less diameter than the shafts or bodies themselves, and gluedagainst the shoulders thus formed. Motion may be transmitted to theserollers by any suitable means acting on the heads of the rollers, orotherwise.

These music and take-up rollers are show-n 0 beyond the notches j, thusenabling a rollerjournal to be placed between such diverging portions,and then inserted in the notch by In the edge'of the blocks I are 5 g 2QWMMML simply pushing it down or into it, the cap I combination,\vith atraveling music-sheet, of

being forced away from the block I by the pressure exerted upon it bythe journal, and after the entrance ot'the journal into the notchreturning to hold the journal in the notch. The caps I of these bearingsbear directly on the journals ofthe rollers and exert friction thereon,which will prevent the rollers from moving too rapidly, or from movingat all when they are not desired to move.

When a roller is to be removed it has only to be pulled-outward with alittle force, and hence it will be seen that the roller may be eitherinserted or removed without any ncccssity for manipulating the bearings.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a mechanical musical instrument, the

a roller composed of a; wooden or other shaft and heads, and a bodyconsisting of a cylindric shell, ofpaper or other light material,substantially as specified.

2. Ina mechanical musical instrument, the combination, with a travelingmusic-sheet, of a roller composed of a wooden or other shaft, providedwith two heads and an intermediate flange or truck, and a bodyconsisting of a ctlindric shell, of paper or other light material, andhaving a peripherical recess containing a device for the attachment ofsaid music-sheet, substantially as specified. v
